Earth Day was first held on April 22, 1970. It was organized by U.S. Senator Gaylord Nelson and coordinated nationally by Denis Hayes, inspired by environmental concerns following the 1969 Santa Barbara oil spill, with roots tracing back to an idea by John McConnell announced at a UNESCO conference in 1969. The date April 22 was chosen to maximize participation, and the event quickly grew from a U.S. teach-in to a global movement. For context, the first Earth Day saw millions participate in the United States, and Earth Day has since expanded to events in many countries around the world.
